When equipping a weapon with a permanent enhancement i.e. flaming or corrosive then the counter for how many enhancements are added to the weapon gets increased but when unequipping it the counter does not get decreased. The counter in the enhancement menu doesn't show that it got increased but you may find yourself in a situation where it says +0/5 and you can't choose anything...
To do this get a flaming weapon and equip and unequip it 5 times in a row and you can't enchant anymore.
An aside note. Corrosive seems to take 2 enhancement points away instead of only 1 as it should.
