What version of MS Script Debugger do you have installed?

I'm using v4.72 and it seems Ok.

Hi Brahma,

I called up the support regarding the issue. Support Team gave me  "UFT uninstaller.exe" to clean up the UFT installation first. Then installed the new version on to my PC.

Also, you try to minimize the Number of applications opened on your PC including your outlooks. It helped, as UFT uses lot of Memory.

Hope it helps.

Hi there.


I have recently opened a ticket regarding this issue. Indeed it is a nuissance.

However since they did not come forward and say "We know we have an issue there", or at least provide a suitable solution, all I can advise you  is to DEBUG SLOWLY!!! Dont tap F10 like a marathon runner, press slowly and it will not get stuck.

Otherwise, if UFT does get stuck. your tests will remain in locked mode when you repoen UFT and you will have to physically find the test folder and delete the .LCK files...

Or even wrose if you are running via ALM, then it's a totaly different adventure...


Good luck friend. And debug slowly...

Re: UFT 14: Uft hangs when debug mode is used.

This is a frustrating problem! It would be great to get this fixed.

I don't even push f10 very fast, but it seems like if I don't wait almost a full second between taps UFT will freeze. Is there anything else I could be doing wrong (or any settings I can change) or is this just something that I have to live with? I hope MicroFocus will take a look at this bug in a future release.  The application should be able to handle a user tapping f10 fairly rapidly. There have been numerous occasions where I've lost work by having to go to task manager and force close UFT.
