I have fairly fast PC and I have issue with Dopus find dialog appearance - after I press ctrl+f, it takes about 4 seconds for dialog to appear. Every time! Could something be done about it? Procmon doesn't report any activity in Dopus during that time...
And one suggestions - could you consider multithreaded find?
Would it be possible to generate a Process Monitor log of what happens when the Find panel opens? (Make sure the log records a case where it opens slowly, of course, if it isn't always slow.)
I will do that as soon as the delay gets bigger; at the moment, it's about one second, so it would be difficult to catch something... Last night it was exactly 4s. I cannot think of anything that has changed to produce different delay (PC hasn't been rebooted and exactly the same apps are opened).
