I am using a HP Desktop 400 running Win 10 Pro (kept up to date) using Aff Pub v 1.10.1342 with h/w acc OFF. Norton runs in the background. No other equipment connected except printer.
Programme opens file correctly and operates as expected - until I start to use keyboard arrow keys to position the cursor at text I wish to delete. Repeating the keyboard stoke (eg left pointing arrow) several times causes the problem. The programme then just closes by itself so very recent changes made are lost. This happens each time I open the file. Sometimes the recovery programme captures changes as this is set at every 300 seconds. In all other respects, the programme behaves correctly. The file is too large to send as it is a draft for a book containing text, graphics etc., which anyway I would not wish to send as you will appreciate. So file attached is with most pages deleted (file name=AP problem). The problem happened on right hand page after about two minutes when editing.
I have uninstalled and reinstalled AP. If I close and re-open the file, the problem still happens no matter which page of the publication I use. This behaviour only started to happen recently and does not necessarily occur straight away.
Any thoughts please as it really prevents proper use of the software?
