Problem with non-stop scrolling of the ComboBox drop-down list -

Hi!
I ran into a strange phenomena:
After clicking on either the spin buttons (the small triangles) or the
scroll bar itself of the drop-down list of a combobox, the scrolling
doesn't stop until the list end is reached. The scrolling stops when
the mouse pointer leaves the scroll bar area.
The application receives messages (via the serial port). The module
that handles the received messages is laced with DoEvents. When no
messages are sent to the application (the transmitter is turned off),
the combobox functions properly.


The application is VB6, SP6, under Windows XP, SP1 with 512 MRAM
memory.


Your help will be much appriciated.
Amir
