I have Windows XP Home SP 2
When I close my browser Internet Explorer I get an error message IEXPLORER.EXE
0x03d74de1 at 0x00000000.
Click OK to close. I do this & it closes.
All works OK after. Not a big problem but irritating & may be a warning of a bigger fault.

I had this recently, too.

I emptied out ALL the temporary internet files, ALL OF THEM. A complete wipe. The problem has gone on my system now.

TOOLS > INTERNET EXPLORER > BROWSING HISTORY > DELETE > DELETE ALL

Thanks for your note.
I deleted the temporary internet files but the problem is still there.
I found another suggestion to find & disable the add ons in IE. I tried this but most of them I think I need & the doubtful ones I disabled had no effect either.
I have decided to live with the error notice but thanks again for your advice & Best Regards.

Try UPDATING all your addons. Maybe updating your Flash and/or Java installation. Maybe their out of date. Grabbing at straws now.
