What steps will reproduce the problem? 1. GUI2EXE v3 2. py2exe setup 3. enter the boot script 3a. enter the full path as given by the directory picker -> syntax error: quotation marks are missing ( from the exported setup.py"custom_boot_script": C:\dir\script.py) 3b. add quotation marks manually -> custom boot file is not a valid file 3c. enter the name of the boot script manually without path -> custom boot file is not a valid file

Otherwise your GUI2EXE really helps playing around with all the parameters.

It should be fixed now in SVN, thank you for the bug report!
