Problem with GUI?

Hi All

I am facing a strange problem when doing a Ctrl F search on ABAP editor (SE37, SE38 etc)....no matter which key I type, it is only typing numbers and if I keep pressing the same key again and again, it types the numbers 1 through 0 in order. I am not sure is this is a setting or if it is really an issue....i tried uninstalling the SAP GUI and reinstall it, but the problem persists...anybody got a clue?
