I see, I'm not sure cause I don't recieve those exact same errors, but my system is as you described it.
What I mostly do is hold the shift key as I delete a file. This method by passes your recycle bin and gets deleted fully.
Well as fully as possible without using shredding.
There are some recyle bin options that offer the ability to delete things without prompting, but since your only describing a read only problem then I won't write them here, but I'm sure they can be found under the recycle bin properties.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
