My problem is this:
I add module to page, hit settings button, make some modifications, hit save. Back to the page everything is there and OK. Hit refresh, module is gone. Hit refresh a couple of times and it is back. Change other settings, such as module container. Hit save. Back to page, everything is OK. Leave the page and come back. The module is back to its previous container, not the last one I set. Hit refresh, module is back to normal. Hit refresh, module is gone.

The same thing happen with pages and files. Youc create a new page and it is there for 1min and then it disappear. Play around a bit and it reappears. You upload a file, everything is going good, suddently the file disappear from the list. Hit refresh and is back.
After a day or two, if a go back to these modules or pages, behavior is ok.

Does anyone have seen this kind of problem? It's dirving me nuts !!

Thanks
