Some 0.9.5 problems

At first my problem with the "remember me" at login (http://modxcms.com/forums/index.php/topic,11762.0.html) is still unsolved. It must be a problem with the cookies but why the cookies needed are deleted automatically?

Second: during content managing the document tree randomly folds up. [solved partially, please read 5th post]

Third: Why modx can’t remember the sort order of the document tree? I set it to "menuindex - ascending" and everytime I log in the tree is sorted by "folder - descending" (also after the second case).

Can somebody help me please?

[This point is SOLVED, please read the 5th post] >:( More and more problems.

Can’t delete documents. What the hell is with my system?
My test system was a local modx installation with a database at the provider outside. Worked fine (except the problems described above).

Yesterday I saved the database at the provider, deleted all tables and installed modx at provider’s web space. Reset of database was ok. System worked ok but now I can’t delete documents. The deleted document gets a line-through marker but can’t be deleted definitely. The trashcan symbol says that no documents are available to deleting.

I’m very confused.

An addition to the second "problem": [solved partially]

during content managing the document tree randomly folds up

I used the "expand all" button to see the full tree. After editing a page and saving it the tree folds up. If I open a folder manually by clicking the plus sign it stays open after editing documents. It’s ok for me now but: why the tree folds up if it is opened by the "expand all" button?

And an addition to: [solved]

Can’t delete documents. What the hell is with my system?

It is solved and was based on following: I duplicated a folder with some documents in it. Then I tried to delete some duplicated documents. But this documents have had all the same alias names like their original documents because I doesn’t edited the duplicated docs before. And that was the problem.

There should be a feature in future versions of modx to modify the alias of a duplicated document automatically, maybe by a "-2" addition or so.
