textpad 5 generated an "unexspected and unrecoverable error" with a large data file of mine and at first i though it was due to length. (1280 lines, 188kb) but there are much bigger data files involved. (5 to 6000 lines and >30000 characters in one) it gives out e dmp file and "unexspectedly" closes without message. no other tried out file did this, nor did any other version of textpad (3) or any other editor. (notepad, notepad++…)
i was able though to load the file as admin and navigate through to the last line, at which textpad crashed in the same manner, so i had a clue; said line had only spaces as invisible characters and no special characters that made any problem elsewhere that i know of -i'm using textpad for at 15y now-.
i didn't figure it out, but if i only typed an x as last character and saved, the error did not occur again -testing several times- because when i erased it, textpad crashed again. also i could erase the whole line (success!) and retype it bit by bit whithout changing a single character and it will crash again; i transferred the line to another place in the file and that worked for me but now i'm convinced textpad 5 is buggy.
i also changed logon and started system several times to no avail.
