strokeit and windows 64bit apps

Hi, I've recently migrated to Windows XP 64 bit and I've been noticing that sometimes 64bit applications will immediately close upon making a strokeit stroke over them. There's no crash, no error messages, nothing, the window goes 'poof' and so does the process thread.

Is anyone else experiencing this? I've so far confirmed with: Mozilla Minefield 64, Photoshop CS4 64bit, any Java application runing on JRE6 64bit.

Im running on an nVidia Quadro card and tried with various recent nvidia drivers.

thanks.

A bit more info:

Im entering strokes using the 'middle mouse' button, drawing the stroke on screen is disabled.

I've used strokeit for many years now, Im totally addicted, and this is the very first time I'm having any problems with it... I really hope to find help, otherwise I'll just have to stop using 64bit apps :)

Thanks.
