Find button states not updated on switch to Transform backslashes

[ProgerXP]

1. Open Find
2. Enter } into the search string
3. Enable regexps - buttons will be disabled because it's not a valid expression
4. Now enable Transform backslashes - the expression is now valid but buttons are still disabled

Fixed.
Step 2 should be read as "Enter \ into the search string".

Related bug so posting here.

Buttons are not updated when the input's value changes using the combobox. For example, enable regexp mode, enter [ into the search input then switch to another value from the history (which is a valid regexp) with the arrow button and mouse - now Search String is valid but buttons are disabled anyway.
