Can't save or load files - program hangs in an odd way

SharkD shared this problem 13 years ago
Answered

When I try to load or save a file, the program hangs (freezes). However (and this part is very odd), I am still able to move and resize the window.


I am running Windows XP SP2.

I have updated Java to Version 6 Update 3.

I am using GeoGebra 3.0 (RC3).


Please help!

Move and resize which window? The main GeoGebra window, or the "Open" window?


Also, what happens if you leave it for a few minutes?

The main window.


I just tried leaving it alone for a few minutes, and the Open window appeared. Then it froze again, causing me to have to wait a few more minutes for the program to become responsive again. However, this time the program also ceased to redraw the screen. All I saw was copies of whatever lay beneath it. I was still able to resize and move the windows (both windows this time).Here's a screenshot:

I also noticed that the CPU usage goes to 100% when the program "hangs".

Is there anything odd about the content of your hard disc? I get the same behaviour on my computer (WinXP SP2) if I navigate to C:\. I have lots of small mp3 and bitmaps on my harddisc so I assume it's slow because it's reading sub-directories (but I haven't investigated properly yet).


What happens if you navigate to a different folder (eg on a USB memory stick)?

The symptoms are indeed strange.

I would be trying to find circumstances that cause / do not cause them.

I notice in the screenshot that SharkD seems to be running POV-Ray.

It would be worth trying with only GeoGebra running.

I just tried with all my programs closed and have the same problem. Task manager does *not* show that the program is not responding, and I am able to close the program in task manager. I don't have lots of files, as it's a fresh install of Windows. I also have C.a.R. installed, and am able to load and save files properly in it.

I tried it on my system (XP Pro SP2, latest Sun Java, Webstart).

I've got lots of files too. :D Unable to see any problem.

In the Open dialog I was able to navigate easily through

My Documents, My Computer, C:/, C:/[subfolders] and USB drives.

Opening a file was no problem either.

It implies here:

that it's fixed in Java 1.7. I'll try it now...

I've installed Java 1.7 from here, but my computer is still using 1.6 :(


(anyway, it's definitely a Java bug not a GeoGebra bug: the 1.7 installer exhibits the same behaviour :) )


Anyway, I've found out what was causing the problem: I had an old network drive mapped that was no longer there. Removing that fixes the problem. So check that first and let us know how you get on :)

Hi Murkle


I was being deliberately vague when I said "latest Sun Java".

I've checked and can now confirm I'm using Java Version 6 Update 3.

How does this other numbering system (Java 1.6 and 1.7) apply?


All the Best

Thank you! That resolved my problem.

I don't know - I didn't know about 1.7 until I read the link above :)


I assume 1.7 is in beta and 1.6 is the current version.


(I forgot to put this link in before: https://jdk7.dev.java.net/ )

Hi murkle


Thanks. I've never really understood Sun's renaming/numbering systems.

It all started to go wrong for me when they had to rename Oak. :laughing:


BTW I don't use zip files much so that explains why I didn't see the bug.

Sorry, I'm new to this forum -- trying to reply, but asked to provide Subject -- how this works.

I had similar performance problems. Saw the reference to XP zip file problems and found this reference:

Turning off ip file support in XP made all the difference. Thank you Mr. Gates
