Gentlemen, The Problem is more consisten now and a guess is that it may be FireFox Related.
Using the configuration detailed in my first post for perhaps the third day in the row I have succeeded to Save tiddlywiki regularly and Lessbackups plugin seems to be doing its job. Only problem is this lasts most of the day Three backups. The Last was at 4:16pm and I continues to update my TiddlyWiki with Critical end of day notes. at 5pm I try ands "Save Changes" and I got this error I have seen before; [Exception... "Component returned failure code: 0x8007000e (NS_ERROR_OUT_OF_MEMORY) [nsIConverterOutputStream.writeString]" nsresult: "0x8007000e (NS_ERROR_OUT_OF_MEMORY)" location: "JS frame :: chrome://tiddlyfox/content/overlay.js :: <TOP_LEVEL> :: line 101" data: no] I then find the primary file on Disk to be 0 bytes in Size, this gets synchronised with Drop Box and even the less backups copy (the d21 one) is 0 bytes in Size. I have to shut down Firefox- or any other open in firefox before I can update my tiddlyWiki- which suggests FireFox's running was damaged. This is difficult because I have to try and establish the changes between the 4:16 and 5:01 from memory. This now implicates - FireFox (unlikely) but more likely TiddlyWiki 2.7.1 or TiddlyFox 1.0alpha12 in my current woes. I am almost crying now ! Any leads you can give me ?
