I just tried to update PTB and got the following output: \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* > \>\> UpdatePsychtoolbox UpdatePsychtoolbox(' c:\toolbox\Psychtoolbox\ ') About to update your working copy of the OpenGL-based Psychtoolbox. Will execute the following update command: svn update "c:\toolbox\Psychtoolbox\" svn: Error resolving case of 'c:\toolbox\Psychtoolbox"' Sorry. The update command failed: svn: Error resolving case of 'c:\toolbox\Psychtoolbox"' ??? Error using ==\> UpdatePsychtoolbox at 124 Update failed. > \>\> \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* c:\toolbox\Psychtoolbox exists, and PTB is otherwise working fine. Subversion is installed and I have updated previously. I tried searching the forum but could only view one page of hits for 'UpdatePsychtoolbox'; clicking on the next page arrow took me to a search page that doesn't work (no idea what that's about). I do note that the error is reporting the path with a mixed bag of quotes which may be relevant? That's nothing I'm doing, I tried calling UpdatePsychtoolbox with the path specified and got the same thing. There's also nothing in the UpdatePsychtoolbox.m file that's appending that extra " at the end, so it may be a subversion thing. I'm on WinXP, currently running Matlab 7.9.0 R2009b and PTB version 3.0.8. (Build date: Aug 17 2009). Thanks! -andrew
