1) It would be nice to show the CPU load under
Windows. The system monitor uses up a lot of
resources, particularly during startup or when
the window is moved so it would be nice to not
have to use it. Maybe there is a dll somewhere
that could be used to get this info?
Leif,
I don't know of any DLL tha can do that, but I can offer you the code I use
in Winrad for that purpose.
Let's hope that the mail system does not wrap lines where it shouldn't, making the code almost unreadable. In any case I
can send it to you as an attachment. Let's first try with the mail...
