Let me see if I understand what happens.

if you save a file in Portabase with open office spreadsheet format it lock portabase and save a file as: (.~lock.BudExp311010.csv#).

As I mentioned in my previous post, Portabase open file manager with a very limited content. In folder N900 it shows one file with my file name (BudExp dated the day the problem occured).

My action to solve the is:
I delete the lock file (see above)
I click the one file name.
result: EVERYTHING IS BACK TO NORMAL. Even all the filtering I have made is there.

So now I wonder is this Portabase' way to solve the problem, creating a lock file and another file to rescue the portabase file? if this is the case it should be mentioned in the help file.

It would be very nice if jmbowman could comment on this.
