I'm confused.
Not a general problem?
What would you call it when multiple people from varying areas and computer types/operating system versions have the same problem then?
What is your definition of a general problem?
Generally, when multiple have the same problem, even if at least one of them (that'd be me) solved the problem without knowing how, that doesn't make the experience any less valid.
I'd certainly classify this as a problem, regardless of your definition of general.

This problem isn't complained of in other programs.  there is no reason to
believe, based on what has been said and not said, that this is a general
problem.

Hi All,

Try booting your computer.  Start NVDA.  Kill any unnecessary
processes from Task Manager (Acrobat, Dropbox, iTunes, etc), and then
launch TB.  Chances are there won't be a lag.

Start up the apps you can't live without one by one, and as soon as TB
lags, you'll know who the culprit is.

HTH!
