I have built an Excel 2003 form with a number of simple controls however when I load the workbook I am getting a mixture of core excel errors from "catastrophic" to "file/path" errors to just a note saying Excel has encountered an error do I want to post it to Microsoft!

The form works fine if I close down excel completely/reload, then load up the workbook again.

I have VB code showing the form automatically at startup in the Workbook_Open() sub. Have tried 'Unload' but this does not cure the problem.

Any ideas anybody - very frustrating!
