For some obscure reason, now it wants to process the document or verify signatures when i open the document. ....... and I have to sit there and wait ! .......

That's not what I want.

I want it to poen in less than 1 second.
Then I want to check something on that document (think like paper document" in 2 seconds.
And then I want to close it again in 1 second.

Your are not doing that ! ,....... you're stealing my time.

And I don't care if it is the document that's the problem.

Because I just use kofax or Xchange viewer instead, they open it right away without expecting me to wait.

If you need to process the document, do that in the background (while you keep it read only maybe).

Additionally the program is (also document related) sometimes simply crashing ! ,........... Maybe because the document was created or updated by kofax or xchange before,....... but you realy have to pull yourself together and make sure you test your product for such cases.

Otherwise, you will be out of this business in some years from now.
