Well, I only noticed 3, none of those running QPC under Windows. And I currently do not have any further ideas in this area because the things told do not add up: - Fast key repeat and fast cursor flashing is a sure sign of increased poll frequency. - The poll test program though apparently testifies to a steady 50hz poll. - If the frequency actually is increased and the test still shows 50hz, the time base of the test must be off in the same way. This would be the SMSQ/E clock. - But apparently the SMSQ/E clock is also not faster than real time. To the last point, regarding this comment from Norman: | I left it running for 15 minutes and it kept exactly the same time. What I should probably have said is that QPC does re-synchronize the SMSQ/E clock with the system clock once per minute. So even if the clock is runaway fast it will be right again one minute later. > My problem is that sometimes the cursor will not remain where it is > placed, by the mouse or cursor keys.

Well, QPC does not use any relative mouse movements which could explain the behaviour, instead it uses an absolute mouse positioning scheme. Basically the Windows mouse coordinates are directly translated to the SMSQ/E mouse position. Therefore my first guess would be that you're using an optical mouse that has problems with the surface it's on. The second guess is that something strange is going on on the SMSQ/E side of things. Did it ever happen on a clean machine? Marcel _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
