My Excel (2003) has developed a very strange problem, whenever I open a file, be it Excel workbook, or CSV etc. I permanently have the right click menu up as though I had just right clicked on the last clicked cell. This is extremely annoying as it makes it almost impossible to do anything.
I have tried, disabling all the addins (both com and otherwise) with the exception of MZ tools. I have tried repairing Excel, as well as removing it and reinstalling (only the excel component of office) to no avail. Any ideas how to stop this behavior, other office applications are not behaving in this strange way.
