i've had the problem and it can be one of two reasons:
1. having a function that runs and runs in the backgroung - press CTRL-break to check that
2. oddly, my sheet has disappeared from the tree of objecxts, when i look under ALT-f11. this seems to be some excel corrupion because the sheet is not hidden.
best to restart excel altogether
and probably to copy-and-paste all the info to a fresh file...
