Annoying DebugBreak (int 3) inside VBOXMRXNP.dll

[StSlam]

In the process of debugging my application, when working with WindowsAPI, an annoying debugger stop occurs due to the fact that your dll causes an int3 interrupt (i.e. DebugBreak) For example, when trying to expand the "Folders" combo box in the TOpenDialog
