I am using SDL Trados Studio 2017. I have a problem with confirming a segment with "Ctrl + Enter" key especially when I work with long files. I sometimes takes 20- 30 seconds to be confirmed and the cursor to move to the next target segment...

This happens while I do QA checks also... I go very fast with next next, but it is again a long time waiting problem when I change something in the window and the change button be active and I press on it on the small screen it makes me wait such a long time, also it is the same problem when I press the ignore button unfortunately.

 Sometimes if the file is big and has a big leverage from TMs it takes 3 hours to do the translation but 4 hours or more to deal with f8...

The other functions and  all other uses with Trados are OK but these two things are really so much time taking, miserably slow...

The Antivirus program in my PC is OK and  makes no problem with even very heavy other AutoCAD and OCR softwares..

Do you have any idea of the reason of this problem ?

Thank you in advance!
