[WT-support] OFF Time bar and CW stutter

[Andy Cook G4PIQ]

While trying to get WinTest configured on an old laptop I've run across a problem with stuttering CW (both as sent from the LPT port and in the sidetone generated by the PC). The computer isn't fast (Toshiba R100 1.1 GHz Pentium-M, Win XP SP3, 1.2Gb RAM), but itbs not an old dog either. I've done al the usual stuff of running ccleaner, defrag the disk, checking the disk cache isn't partitioned etc.

I find that I can get the CW to go normal if I turn off the 'How many minutes since last QSO' bar in the status window. Importantly I also find that running that bar raises the CPU utilisation on the computer from around 4% to around 25% which seems an inordinate amount of CPU to just display that bar.

As a reference, I don't see this problem (or the high CPU from the status bar) on a P4 1.6 GHz desktop. Win Test version is 4.4.0 in each case.

Are there any extra dependancies on the machine that I'm missing here. I presume Win-Test doesn't place any requirements on the Java version on the PC (this machine has had a few different versions of Java for work - otherwise it's pretty normal). Or maybe I just have to build that WinKey unit I have in the cupboard... But then I have to sort out another working USB-serial adapter!

73,
