Hi all,
I'm using IDL 5.4 on a 2.4 GHz Pentium 4 with 1 GB of memory, running
Windows XP. It has a GEForce 4 MX 420 video card with 64 MB of video
memory. The last few days, I can't run some of my programs because of
a problem using the function GET_SCREEN_SIZE. It fails when it tries
to realize a widget with MAP set to 0. The given error message is
"WIDGET_CONTROL: Unable to acquire a GL context".
I've tried reinstalling the display drivers, to no avail. I have the
exact same problem on my laptop (1 GHz Pentium 3 with 256 MB of
memory, GeForce 2 Go video adapter, Windows XP). I suspect the
automatic Windows XP update has installed something that is screwing
things up. When I use Windows' spectacularly unhelpful display
troubleshoot feature where you can disable hardware acceleration, I
can get things to work again if I disable "all but basic
accelerations", but if I change this to "disable all DirectDraw and
Direct3D accelerations, as well as all cursor and advanced drawing
accelerations", the problem arises again. I can also get things to
work if I set the default IDL object graphics renderer to software.
I'm just curious what happened to cause this problem.
If anyone has any sage advice, I would be most grateful.
Ted
