Do you have only limited RAM? Cause I've seen this quit-to-desktop behaviour when I didn't have enough memory for an app that used to call an external DLL, along with the use of the XLnt Gui, that is probably (likely) using handle and object too.
Personally I never use handle nor object, I even tend not to use types - so I never experienced any problems with them.
