I've uploaded an updated version of the CommandBar dll, can you please download both files from here:
www.basic4ppc.com/files/DBasic.zip
and replace the existing files (Dbasic.exe and CommandBar.dll under Program Files\Anywhere Software\Basic4ppc Desktop).
This is the trial version so it won't be able to compile.
Please check if it works properly on your machine.
Thanks,
Erel
