Summary0008569: Removing a script with llRemoveInventory after a touch start event lets you left click and drag the prim.
DescriptionIf you have a script with a touch start event, and then use llRemoveInventory to remove that script the object is left in a state where you can left-click and drag it.
What is worse is that anyone can do this, not just the person who owns the prim.

This is not true in 0.8, nor is it true in second life.

Video Demonstration: [^]
Steps To Reproduce1. go to a region running on
2. Build a box
3. Add the following script.

    touch_start(integer any)
        llSay(0, "watch how you can move me after this!");

4. Click on the box
5. Hover the mouse over the box again, left click and hold then drag the mouse around.
6. Repeat the left click and drag from another avi with no edit rights etc
Additional InformationAdding another script with a touch_start event will stop the issue. However, if you remove the script, even using the viewer anyone can once again move the prim about. If the new script is later removed the issue returns.

This also affects .net as well as mono.

note that i only test current dev code, version 0.9.1
this does have a lot of changes and fixes since

so this may had already changed and what i seen was identical to SL

i.e. doing left click and moving the mouse holding the left button the prim does move.
on a second click and drag, there is no movement.

this also happens at SL.

never seen a avatar with no move rights move the prim

even seeing the prim move at SL in this case, i did code changes to avoid that.
A non physical prim is not supposed to move by mouse drag unless with the move tool (cntr + 2) active or edit
Now if there is a touch event (any of the 3) triggered, prim drag is blocked unless it is Physical. (all this was about non physical prims)

thank you for looking at it and fixing, I have no idea why you got different results to me testing on the older codebase. Anyway, its fixed which is all that matters.

as I said, possible because im testing in version and you on ?
you can test 0.9.1 for example on a osgrid sandbox plaza ( still without my changes from yesterday)

I have very similar bug with current master (2019-08-07 20:06).

How to reproduce:
- create 2 prim and link them.
- put this basic touch script on root

    touch_start(integer n)
        llSay(PUBLIC_CHANNEL, "Touch!");

- clic link 2 (keep clicking) and drag.
