Since patch 1.5 my inventory menu appears to be much slower.

After hitting "tab" the menu appears instantly, but when moving to the menu's themself (magic or items), there seems to be a delay of about 1 second before they appear.
Same goes for equiping or dropping an item , a delay of about a second. (just scrolling in the menus works fine)
And again the same for the favorites menu, delay before it apears and when I equip something.

Main menu/options menu etc. work perfectly fine.

I've been playing Skyrim since its release and the inventory had been working smoothly up until now....

Anyone experiencing the same thing? or any suggestions on how to fix this.

Nevermind, I started a new game to check the remote possibility that the problem was related to my savegame. (previously checked the last 5 saves, without luck). And everything worked perfectly well

Then I tried a few old savegames, and the work as well.

So, apart from losing about two hours of game-progress, and having to replay a few quests, everything is fine now

Long time user of SkyUI and Categorized Favourites and no noticeable difference for me with 1.4 vs 1.5, if that helps. What mods are you running?
