Has anybody had this problem and solved it?

After (finally) getting Gigastudio up and running, I\'ve noticed that when
SONAR is running at the same time, MIDI response gets slower over time,
finally getting to the unusable point.

To be more specific, I start GS and load an instrument. Everything\'s fine.
Then I start SONAR (from GS) and play my MIDI keyboard with a track assigned
to one of the GS ports. At first everything\'s fine, then delays between
hitting the key and hearing the sound start to build up. If I shut down
SONAR and start it again, there\'s a big improvement - for a while.

This happens only with MIDI transmitted from my keyboard. When I click on
the keys in the Piano Roll View (or click on the GS virtual keyboard), the
response is instantaneous.
