Hi - don't know if anyone else is having this problem but PBb5 and PBb6 seem to object to some commands and need to be rerun before accepting. I generally get this using Openwindow, For..Next and Swap. The compiler will say there's a syntax error up to three times and then finally compile. I just keep hitting F5 until it goes. Can't reproduce this since it's rare and with different commands. Havn't installed PBb7 yet so don't know about that version.
