Problem with GfxTools under Vista

[Aldo Vitagliano]

An user of my software pointed out a severe problem arising under Vista (everything is OK under XP, where I developed the software).
To make it short, I could reproduce the problem and then I squeezed it in the following short and simple sample code.
When a key is pressed or mouse is clicked, the graphic window is cleared and a circle of random radius is drawn, BUT ... under Vista if a mouse button is clicked the program hangs.

[FONT="Courier New"]
$INCLUDE "C:\GFXTOOLS\GFXT_STD.INC"
$INCLUDE "C:\CONTOOLS\CT_STD.INC"

FUNCTION PBMAIN()
   ConsoleToolsAuthorize %MY_CT_AUTHCODE
   GraphicsToolsAuthorize %MY_GFXT_AUTHCODE
   InitConsoleTools hCurInst&, 0, 0, 2, 0, 0

   MOUSE 3, DOWN: MOUSE ON
   CONSOLE SCREEN 25,81: SLEEP 300
   GR& = ConsoleGfx(1,1,81,25)
   R& = GfxWindow(%GFX_SHOW)
   DO
      GfxCLS
      RADIUS&=RND*200
      DrawFrom 512,256
      DrawCircle RADIUS&
      V$=""
      DO WHILE V$=""
         V$=INKEY$
      LOOP
      IF V$=CHR$(27) THEN EXIT FUNCTION
   LOOP
END FUNCTION

How to fix this ?

Aldo --

That program runs fine on my Vista system, and (for what it's worth) nobody has reported any Graphics Tools problems related to Vista. In fact we haven't found an actual GT bug in over four years now.

This issue may be specific to your user's graphics card/driver (for example it might be rejecting your request for a nonstandard 81-column console), or it could be a number of other things.

Rather than go back and forth with various questions/tests here, please contact me at [email protected] and we'll figure it out. For lurkers, I'll post the final results here, when we are done.

OK Eric, thanks. I did as you suggested.

Nevertheless, I believe it will be helpful if members of the PB Forum could try the sample code and report whether or not they see the problem.
