export layers to files is merging each layer with one other layer on export. I have a bunch of text only layers and half a dozen regular image layers. I'm exporting png24. I've used this feature extensively and today it starts doing this. I finally found a work around - I put a blank text layer at the bottom of all my text layers and at least now I can't see the overlay. Also, export layers to files only seems to work right if I set my visiblity and choose Visible Layers Only. Any other choice causes the program to terminate early with some sort of "delete isn't available" or something.
For the layer merging issue, do you happen to have a group in between two non-group layers? If so this is a known issue that I will raise in priority. For the hidden layer issue - I've reproduced with a group. Non-group layers are working for me. I'll open a bug for this. Thanks, Eric
