Viewpane locks files but doesnt unlock them

this is probably the wrong lingo, but i'll try to explain what I mean...I use the viewpane fairly often but ive noticed that when i view some files dopus never closes the handle and therefore i cant change the file after that. here's an example...i create a file of comma-separated values, switch over to dopus to check it out, see that its in the folder that i intended it to be in, open the file in the viewpane (nothing fancy, just the text viewer plugin), close the viewpane, then try to edit the csv file but i cant because its locked. i can then go to somethign like process explorer and look and sure enough the dopus has the file locked. in order to do something with the file ive got to close the handle.

is this normal?

It isn't normal.

Disable all plugins and see if the problem stops happening. If it does then enable them again until you work out which plugin is creating the lock and failing to release it.

(Other plugins may look at the file before the one which views it.)

Also check that it doesn't happen if the viewer isn't used at all, in case we're looking in the wrong place.

It doesnt happen if I dont use the viewer.

I deselected all of the viewer plugins except "text" then opened the viewpane on a .csv file, closed the viewpane, then checked the process explorer and the file was not opened. the same happened for every other viewer plugin EXCEPT the MultiView plugin. When i enabled it and opened the viewpane then closed the viewpane then checked the process explorer, i saw that there was still an "open" handle or dll for the file i was viewing.

this is screwing me up n a number of fronts so im glad to hear its not normal and possibly can be fixed!

If you configure the MultiView plugin does it say it's using viewer DLLs in a particular place, or that it can't find any?

Viewer DLLs located (8.2.0.4673). These are some filters that i copied from stellant something or other (its been awhile, but i followed the instructions about how to obtain these quickview dll's from somewhere on this list a few years ago).

are these outdated or something?

I don't know much about different versions of those DLLs but the file lock is probably happening inside them so it might be worth trying a different version if you can find one.

Sounds like a good idea. I'll look through the archives here and track down these stellant filters and see if i can find some new ones. Thanks for your help.
