>>Yesterday I upgraded VFP to the last service pack from VFPX, but since then I cannot edit or run any reports. When modifying a report file, VFP shows a shadow container and hangs. Any idea what might cause this problem?

I uninstalled VFP, removed all DLL's from Common files, and then reinstalled VFP and applied the hotfix again.
Now it's all working. I think you're right, must have been something else causing it.
