Jason,

GOOD MEMORY!!!!!! Yes, I disabled the toolbars on this particular project.

Made me go check another project that uses the toolbars...no problem with that application. Message comes up and when I press OK the message dialog goes away and I get returned to the first copy of the form. Life is good in that App!

It's just when the toolbars are disabled...you on to something here?

Scott
