Re: [ROOT] Strange TApplication timing

Hi Valeriy,

The problem is situed into TGWin32ProxyBase.cxx :

Into TGWin32ProxyBase::ForwardCallBack(Bool_t sync) :

This piece of code is producing the reported behaviour :

      // wait because there is chance that message queue does not exist yet
      ::SleepEx(50,1);
      if (wait++>5) return kFALSE; // failed to post

But, as far as I can see, the problem occurs only on NT, not on XP...

Cheers,
Bertrand.
