Dll for Kit

[Gintaras]

Then probably thread that called OpenDevice or KitInit must be running all the time.

dialog:
mac "kit_thread"

Function kit_thread:
KitInit
atend KitInit 1
wait -1

For kit_thread check "Allow only single instance".

Or, let the dialog run all the time. Instead of closing - hide. Next time, if dialog exists, show it.

Or try this:
DisableThreadLibraryCalls GetModuleHandle("K8055D")
Then the dll will not know that the thread ended.
