When I start up Indesign My cursor gets a blue windows loadingsign next to it and they both keep flashing on and off. I I try to klik on a menu it imediatly closes as if I clicked somewhere else to. If I want to enter text, I cannot type,...
I made a little screenvideo of this problem : Indesign on Vimeo
My other apps don't have this problem. I erased Indesign and installed it again but that didn't help.
I hope someone can help me solve this problem?
I see you're on Windows.
This happened to me with Illustrator.
It's caused by Adware called Webcom by Lavasoft.
Uninstall all this software by Webcom or Lavasoft and see if it fixes the issue.
Malwarebytes is free for 10 days which can do it for you.
I recommend doing it manually though.
Let me know if you require further instructions.
1) Close all Adobe applications and confirm from task manager if all the applications and processes related to Adobe are closed.
2) Click notification area and check if there is any application like webcom, if yes please right click and exit.
3) Open programs and features from control panel and uninstall webcom adware from lavasoft.
4) Relaunch Indesign and check.
Please feel free to revert if issue still persists or contact support as suggested above.
