Since I started using the VillageTronic VTBook card in my laptop to enable a 3rd monitor (laptop screen + 2 others) I occasionally get a message saying there is an error loading OpenGL. After that, anything I do that would cause a dialog box to open hangs Matlab.
The problem seems triggered by the PEAKS function.
>> peaks(30) Warning: Error occurred while loading OpenGL.
If I issue the OPENGL NEVERSELECT command first before plotting, then I receive no error. If I use the OPENGL SOFTWARE command then I get the same warning as above plus an additional line:
>> peaks(30) Warning: Error occurred while loading OpenGL. > In opengl at 75
My graphics card information is:
Version = 1.3.4145 WinXP Release
Vendor = ATI Technologies Inc.
Renderer = MOBILITY RADEON 7500 DDR x86/SSE2
When I type OPENGL INFO to get my graphics card information I received a segmentation violation:
