glad to help ! I am not sure why this happens .. that is the big question .. I have even had times where I cant save , then diasble some program, like maybee NOD32 , then save , turn NOD back on , can save normmally , even now that the offending program is back on and then never see the issue with that particular file again , some weeks pass by and some other document triggers the fault , I disable NOD32 and can save perfect , turn it back on and cant save again .. turn NOD32 off with that file and saves work fine .. It really drives me crazy from a troubleshooting point of view because the behaviour is not consistant and really tricky to produce on demand . I do not have a list of programs that do this , but so far ZUNE is very high on the list , and infact on the ZUNE support boards , the Microsoft team have confirmed this as a bug .. I personally dont have zune and have never installed it , but this issue came up as soon as I switched from my long time favorite Anti Vrus ( AVG 7 ) over to Avira Anti-virus .. Since that was the only recent addition , I quickly suspected it as the source of my troubles .. I then had need for a clean install and decided to try out NOD32 , (thinking I would avoid the trouble that Avira aparently brought to my AI life) and found the same issue come about , and when I turn off Nod32 problem gone .. I am just stummped , but at least I can save :) I wonder what other programs might be doing this as well? by the way I am on Vista , so not sure if that makes any difference as well?
