Several New Issues

A friend and I kidnapped a patron from one of the adult clubs and brought him to my compound so we could do some rigorous testing of my various pieces of scripted furniture. We encountered several issues:

1. Attachments capable of detecting/aiming for other residents behaved strangely upon logon or teleporting. My friend's collar kept announcing I was already the collar's owner, and my bullwhip kept asking me to aim at someone. (I saw another thread on this topic already, has to do with sensor events, it seems?)
   
2. Sitting up from simple objects seems problematic. I dragged a 'basic chair' out from the library to sit on, and after standing up from it, I became stuck atop the chair. I could chat with others and they could chat back, but I couldn't move or pan the camera. This happened twice.
   
3. Deleting items in-world doesn't seem to work. I got fed up with the chair after restarting twice and tried to delete it. Wouldn't work. I just took it into inventory.
   
4. Button text for items with menus seems to be truncated. I swear the buttons on my SexGen beds seemed to have fewer letters in them today than they did previously.
   
5. Poseballs randomly not working. On these same beds, say in a threesome configuration, two parties might be able to hop on with no problems, while the third person wasn't able to take the third ball. They'd get a "no room to sit" message instead. Other times, they'd be able to sit, but the animation itself wouldn't take effect, even after disabling animation overriders.
   
6. Increased hangs and crashes. Since I started playing with the new update last night, the SL client has hung ('not responding' in title bar) four times, crashed twice (client terminates unexpectedly), and hard-locked my entire system once. This is worse even than the original 1.10 update. Also, each of the five individuals I spent time with last night and this morning crashed at least once... most of them several times. Two of the crashes I experienced seemed to be the direct result of my attempting to IM one of the people in the room with me. I crashed halfway through typing my messages.
   
7. I was dragging notecards individually from one inventory window into another, and each time I did, the first inventory window would scroll all the way to the bottom, forcing me to relocate my position in it, for every notecard I wanted to drag.
   
8. Another weird thing... not everyone was able to see the same things. For example, this morning I was in bed with two other people. One of them kept asking why I wasn't in bed with them... but I was! Turns out, to him it looked like I was standing in the middle of the room. Next, we were elsewhere and a friend was sitting inside a cage. It looked fine to me, but the other person in the room said it looked like the girl was sitting on top of the cage, instead.
   

We were just experiencing one problem after another this morning and didn't have time to report, but I will definitely be filing bug reports when I get back home.
