This all applies to version 4.9.0 on Windows 7 64-bit

1. Clicking on the quick-access set of items (bottom left area of screen while in game) while in the inventory screen doesn't let you interact with them using the standard menu. This make it difficult, if not impossible, to remove items from there. It wasn't like this in the earlier versions of the game.

2. The roll-over descriptions for the quick-access set of items is cut off by the edge of the screen.

3. The keyboard shortcut Alt+Enter does not resize the window. Most applications map that key combination to the resize command, and this would be preferable for consistency reasons.

4. It would be nice there was an command to automatically put all arrows into the quick-access set of items. Otherwise, as is currently the case, I usually put all the arrow stacks I get from fletchery there myself.

- The menu will no longer draw over things in next release because of a restructured layout.
- The change in the quick slots came with making them a general access method for items, skills and spells. Before that only items could be there.
Skills and spells of course don't have an item menu to open.
It should be not too difficult to also make the quick access slots open the item menu instead of triggering their action when in inventory.
I am unsure though, how an intuitive way to clear a quick slot would look like.
It's not strictly necessary to clear them anyway, as one can assign something else to a slot empty or not.
I think I should make the quick slots follow an item at least. Right now, putting and item into a slot will make the quick slot point at the inventory slot where it actual item is in.
Now if you move something else there, then that item will appear in the quick slot.
This is surely not the expected behaviour.

The abort button in skill selection brings me back to the title screen, as it should.
But I develop under Linux, so it might be a windows only problem.

A special command to assign ammunition to quick slots seems very specific to me.
I might however make the game put certain start equip items into quick slots at game start.
This would then be things like pickaxe, shovel, wands, trap-toolkit and ammunition of course.

As another bug, switching to another process using Alt+Tab in windows 7 causes the game to crash.

Ah yes, indeed.
This screen has been reworked already and problem is gone.

As for the crash, that does not happen to everybody.
Works fine for Zefz (Win 7 x64) and me (XP x32).

This crash happens only in fullscreen mode. And it is not really a crash. Rather, the game freezes and becomes unresponsive if you tab out of it from fullscreen mode.
