Well we are going to learn nothing from your about what occurred are we. as your the only one I have seen with such issues they are likely to be permanent. SO much to the upgrade path.

So are you going to update so we can work on it or is Version38 going to ne your last?

Images column 1 and header 1 are from v37. Note the columns. Also note the message header. columns 2 shows the column headers from freshly installing v45 with added "Tag" and "Location" columns. columns 3 shows the same header after clicking on a different folder and immediately returning to the modified folder. Note the new headers are gone. header 2 shows the exact same header as header 1 (from v37). Note all data is missing. If there is some specific information you need to help with this problem, let me know, I've exhausted my limited abilities to address this.

I am thinking there is some preference or settings file that is corrupt. I have tried deleting a couple without success. If anyone knows where the pref/set files for columns are stored, please let me know.
