IndexOutOfBoundsException thrown while searching

[SimonIT]

I opened a big csv file (71.36MB). Then, I wanted to search a text and the exception was thrown.

java.lang.IndexOutOfBoundsException

Thank you for your report. I'll try to look into big files in next version.

As a workaround for now I suggest to switch to memory mode instead of delta mode - in options or in bottom right corner next to INS/OVR (popup menu). Whole file will be loaded into memory thou.

There could be multiple reasons for this issue:

• There is maybe an issue in delta pages handling (partial memory loading)
• File was changed while being edited - current version cannot handle such changes and also files locking is not implemented

I tried to look into this, but it seems to be some kind of race condition when performing search. I'll check it in future, in version 0.2.2 it should throw different error thou.
