screenlets reposition if autostarted

Same thing here on ubuntu 8.04 (standard).
Sometimes some Desklets start in the upper left corner even though they should be somewhere else.
Very random! Amount and selection of these Desklets varies, but it seems that the Desklets which are first loaded are missplaced more often. The desklets which are loaded at the end are never missplaced (I am running about 8 Desklets).
This seems to happen only on autostart. After that I can type a "gdesklets restart" or "gdesklets slay && gdesklets start" (even a few times) and everything works fine again (no missplaced Desklets).

More news:
when restarting from terminal and using the workspace switcher things are getting - most times - messed up, too. Even the Desklets to be loaded at the end can be affected when switching workspaces.

And even more news:
bringing down things to just one workspace: trying to switch (using keys) doesn't affect the Desklets (probably as there is no switching ;) ).
Back to more than one workspace: switching workspaces messes up the position of some Desklets.
And even with only one workspace left some Desklets are randomly miss-positioned on auto-start.

Well, I still cannot figure out what is causing this problem, but it got worse here on my ubuntu system.
Strange thing, too: this doesn't happen (never ever until know as far as I remember) on my gentoo machine ?!

Anyway, all I could think of right now would be a dirty hack like a startup delay from within gdesklets (configurable). But this would really be a bad and dirty hack (if it would be working at all ?!) ....

Any opinions or other ideas on this one ?
