Hello M.G.,

I have an idea (more an intuition) that my video card drivers might be causing a problem.<!-/quote-!><hr size=0></blockquote>I almost mentioned this earlier as a possible explanation of the problem. Some other users over the last couple of years have reported conflicts between video drivers and MIDI device drivers, that were resolved sometimes not with updating the MIDI drivers but with updating the video driver.
