destroyonhide=true in gui causes client.var saving error
 

when, in a gui window, that window has destroyonhide=true,
and other functions controled through the window alter a client.variable,
when the window is closed - the client.variable cannot be read again by any other npc
unless the player reconnects to the server.

if you don't follow this error, i can explain it again ...

What are you talking about? How are you modifying the client.var? How are you destroying the window? Some code would be nice.

the actual npc was 400 lines of code ... but anyways
the window was activated and closed by a keypressed (detect keycode) query.
even by closing the window with the red X in the upper right corner it still caused the client.variable to not be readable until you reconnected to the server with the gui window having the destroyonhide=true in there.
all i did was make it destroyonhide=false and that fixed it.
it's just odd that a window property would cause a client.variable read error and not report it as an error. it just quietly ignores you.

It has to do with how you are setting the client.variable, I really doubt a GUI property would have any influence on it. But I can't help you unless you post some code.
