Thank you. My application locks record in both aliases. Changing UNLOCK command to

UNLOCK ALL

command fixes this problem.

Btw, I described also the following problem:

"Application toolbar docked to upper or lower border in screen is not visible in VFP 9 application running under Windows 98"

I think this is always reproducible.

Shoult I report this to Microsoft as bug ?
