Autocomplete and quick Backspacing issue

On Windows 8, when I use the Backspace key in a quick way in the code editor and the part I’m trying to delete activates the autocomplete ‘ghost’, the IDE hangs and the key is no longer taken in account. I have to slowdown if I want to delete the code.
I’m not seeing this behavior on Mac OS X so I’m not sure if it’s a configuration issue more than a Xojo issue.
Anyone having this problem?

Please see if this is of any help.

Thank you for the info.
