Eclipse Find/Replace not working

Question

I have searched for a solution to my problem but with no avail. The eclipse Find/Replace function found by the hotkey ctrl+F is not working. Note: the function does not work by the hotkey neither by going through Eclipse menu Edit>Find Replace (not working I mean that the FindReplace window does not show at all, the eclipse window loses focus only). I have tried to disable the hotkey to see if it would work, restarted eclipsed, restarted the PC, but nothing seems to solve the problem. It was working just fine but then suddenly out of the blue it just decided not to function anymore. Everything I tried so far has failed. As I use this function often it would be nice to know if someone has another input for trying to solve this bug. I am on a PC with windows 7, intel i7 64-bits.

Answer 1

I had a similar issue after using second monitor at work. At home I was wondering where is my Find/Replace window... it was displayed at the second monitor as I used it last time... Eclipse stores the last location of the dialogs for better UX.

So try to move the Find/Replace window by using your keyboard.

You can also try to reset perspective

Window > Perspective > Reset Perspective...

Answer 2

I had the same issue with Eclipse. My current version is Neon.3 Release (4.6.3).

This periodically happens where the Find/Replace does not work. Usually UNDO stops working also.

When this happens, Ctrl+F, Ctrl+Z do not work, and Undo Text Change and Find/Replace... are grayed out in the menu.

I tried the above solution Window > Perspective > Reset Perspective...

That fixed it right away!

Thanks

When your Eclipse are full with cache that time this problem occurs.

please try to reset perspective setting and then check it.

Just go to menu bar : Window -> Perspective -> Reset Perspective and it will done.
