A while ago I had a HD crash on my laptop. After getting it back with XP Pro reinstalled, it started behaving strangely with DX4Win. Once in a while (3-4 times per minute) the CPU load is nearly 100%, screen updating is hesitating and cursor freezes momentarily.
When I stop the radio there is no problem and the CPU load is only a few percent. I tried different polling intervals from 1000 to 5000 ms - no difference. I was reading the archives and found that this has happened to others, but there was no clear solution. I tried to stop things in the Device Manager and restart them - no difference. There is no difference between DX4Win 7.04.04 and the previous version, so DX4Win is obviously not to blame. If I remove Windows update KB908531 (discussed in the archives), it will destroy a lot of other patches which came later, so I have not done that. Disabling the antivirus program does not make any difference, either. DX4Win works, but I do not like these "hesitations" which can take up to three seconds. The CPU is a 1.4 MHz Celeron with 750M user memory (service Pack 2 and all the patches installed)and the radio is IC-756PROIII through MIcroHam Keyer virtual COM port running latest router software. Any advice is greatly appreciated. 73 Erkki OH2BF _______________________________________________ Dx4win mailing list [email protected] http://mailman.qth.net/mailman/listinfo/dx4win
