In previous Dev C++ versions user can close "Find" dialog by pressing "Esc" button.
In v6.3 it doesn't work that way anymore. The only way to close "Find" dialog in v6.3 is to use mouse cursor - to point it to "Cancel" button (or to "Close" button in dialog's top-right corner) and click LMB, which is much more complicated and takes longer time than just press "Esc" button, especially if you use "Find" dialog frequently.
Hopefully this issue will be taken into account in the next Dev C++ versions.
