i'd like to extract a text pattern from the clipboard and write it to a text file line by line. the Textfile Content in the end should be like this: A1234567890 B123456789012 the clipboard Content could be something like this: bla bla text A 123 123 123 11 11 bla bla return, line feed more text B 12...

found a bug in RegEx Utility, I guess.

to reproduce add this text and expression: Now check/uncheck Highlight all matches
-> high CPU load, OS hangs
