I apologize if this message gets through twice. Hi I am running the Screen command FrameRect on a Macbook Pro, Intel processor, OS 10.4.11, Matlab 7.4. There are two issues I am having: First off, the corners are not corners, rather the vertical sides continue past the edge of the rect creating more of a ladder rather than a rectangle. Second, the frame penwidth does not increase when I increase the number. I have downloaded the most recent version of psychtoolbox so it is not an issue of the corners that have been reported previously. Any idea of how to fix this problem? Any help is greatly appreciated. Thanks Elissa ---

Elissa, i'm confused by 4 different mails. Can you summarize which machines show the problem and which not? Which OS/X version, which graphics card and driver? The output of "PTB-Info: OpenGL renderer is ....." in Matlab will tell the model, vendor and driver version. Can't reproduce this bug on OS/X 10.4.11 PowerPC with old NVidia card, or OS/X 10.5.5 Intel with new NVidia card, so its probably something very specific to one card+driver+os+machine combination. a) Does it make a difference if you use a penSize of 1 vs. \> 1? Differnence between even (2,4,6,...) and odd penSizes (3,5,7,9,...)? b) Does setting the penSize with other functions like Screen('DrawLine') or Screen('DrawLines') etc. work correctly or does it fail as well? What you describe is a driver bug, not fixable by us, best we can do is submit a bug report to apple if we have exact details of when and when not this happens, and then sit'n wait for a few months... So your best chance is hacks like using other drawing commands to draw the framed rect manually. best, -mario > --- In [psychtoolbox@yahoogroups.com](mailto:psychtoolbox@yahoogroups.com), Elissa Aminoff \ wrote: > \> > \> Hi > \> > \> I am running the Screen command FrameRect on a Macbook Pro, Intel > \> processor, OS 10.4.11, Matlab 7.4.

I just thought that the developers would like to know that I have the exact same problem, using WinXP on a PC, ATI Mobility Radeon X1400 x86/SSE2 :: 2.0.5527 WinXP Release, Matlab R2006b. > --- In [psychtoolbox@yahoogroups.com](mailto:psychtoolbox@yahoogroups.com), "Mario Kleiner" \ wrote: > \> > \> Elissa, > \> > \> i'm confused by 4 different mails.
