Dear pjo1966,
I would hazard a guess that a re-einstallation of Sidekick may solve the problem, but do remember to back up all your Data first.
I would suggest copying the entire Starfish|Sidekick98 folder to another location first and then you can always put back any Label contents or Envelope Address templates or whatever else you have amassed including expense files or reports etc.
See faq807-2966
especially: Q02 Backing up and Restoring user data in Sidekick 98
and faq807-3000 too
and as I always suggest, save them (the 2 FAQs) for viewing offline.
They contain lots of valuable information.
If the above procedure doesn't work then Post back and we can go from there.
All the graphic interfaces of your other programs work OK do they?
What operating system are you using?
HTH
Regards Jim
