Cannot zoom in

Hello,


I have been having this trouble for about a week or so and it makes using GeoGebra in 3D completely unusable. I simply cannot zoom in. It does not matter whether I turn the mouse wheel one way or the other, it always zooms out. The same happens when I use touchpad. I do not even know what the zoom button is supposed to do because when I click it, everything disappears.


I have already tried using different versions of the Windows application, both with the installer and the portables. It was always the same.


May I ask you for your help, please?


Thank you.

Michal

I'm sorry but am not able to replicate the issue.

Both Win installed and online/offline Math Apps zoom in/out smoothly in 2D and 3D Views

I suggest you to:

- check if your ggb version is the latest

-try another app that uses zoom in/out, to check whether the problem can be related to your mouse/touchpad devices. From time to time it's necessary to check if their drivers are updated, too.

Hello,


Thank you for your message. I have check my mouse and touchpad drivers and I honestly think it has something to do with the graphics drivers. Sometimes it gives me message "Cannot find ICD OpenGL driver". All my drivers are up to date. I have tried reinstalling them as well, both the integrated grahics (Intel HD Graphics 530) and the dedicated one (AMD R7 M370).


All other applications work normally.

The warning message shows a problem with Graphics Drivers.

Try downloading an older driver and check if it works, e.g. from here:

Also try the online version of MathApps

or the offline version of MathApps: see http://wiki.geogebra.org/en...

to find your OS version, and see if it's any better.

OK, I have found the reason. It is a mouse/touchpad related problem. And the same problem occurs in all GeoGebra installer and portable versions 5.X, and MathApps portable versions 6.X.

I have Microsoft Wireless Mobile Mouse 4000 and I cannot zoom in. Using touchpads on 3 different Dell laptops I was not able to zoom in either. It was only with a Logitech USB corded mouse when the zoom-in function worked.

I cannot imagine more specific source. I think you use the same API command as any other application developer. But something is wrong for sure.

Thank you for your help.
