Propertiy - dialog box MISSING

[Gurra]

Dear friends,

By some strange reason my dialogbox - Properties - is gone. I have tried to
reinstall Office and access, but without success. Its not a window - using
Cascade have no effect.
Via "code" i get access to properties, but I need same access via the tool -
Properties, which you find via "Show".

Any idea how to get access to this dialogbox back?

Best regards
