I noticed strange problems in how EE processes regular expressions.
1. Start the portable version of EE 8.04 with clean settings and open a text file with the following contents:>MDB
>Resourse Extractor +
2. Press Ctrl+H, enter the Find expression:
and Replace with expression:
3. Check the Use Regular Expressions checkbox, press Replace All.
4. The result is:>>MDB
>>Resourse Extractor +
You can see that the second line is processed incorrectly.
If I perform the same find-replace step-by-step, I get the same result (in the “NSCopy” string the letters N and S are found and replaced as if they were located at the beginning of the line), though they are not.
I reproduced your issue, and I will fix this issue soon. Thanks!
