twslex,
That explains it. I can also replicate the problem here with php acceleration enabled. I never used php acceleration on my boards due to all the hacks (earlier hacks just didn't like the accelerator). However, for good measure, i'll incorporate a fix for php compatability in the next version release. Shouldn't take me long.
BTW, that line which you recomended earlier -- if it works for you, go with it. But use .cgi instead of .pl. Its the proper way to fix the incompatability for transitions (or turn off the php accelerator). And thank you for tracking down this incompatability!
