cannot edit properly the entries

[José Ramom Flores das Seixas]

Hi,

I'm using gnucash-2.6.1 in Ubuntu 14.04. 
I have three different files, that are in three different directories.

Some days ago, while I was using gnucash, there was a power cut. Next time I used gnucash, when opening it a warning message saying that the file was locked appear, but as I was sure that nobody was using the file I choose to open the file.

Since then I cannot edit properly the entries. I can add new transactions, but if I make a mistake I cannot correct it. I can't delete the written text but I can add more text. However I can delete the transaction.

I have made several tests, and I could confirm that the 3 files are OK, copying them to another computer and to another user account in the same computer, and working with them. So the problem is in my user account.

I have deleted the ".gnucash/", ".aqbanking/" and ".gconf/apps/gnucash", and I have also deleted the recent log files, but the problem remain. 

If fact when I initiate the gnucash it still has information of the last files used. It has lost the format of these files, what accounts where open etc, but it open the last file used and it remember the other files. So there is at least another file that uses gnucash to store information, and I suppose that the problem is there.

Any help is welcome.
