Scilab graphics crash

[David PICARD]

Hello,

In a plot window, when I start the entity picker and click on a curve, 
Scilab crashes quite often with the message :

Warning !!!
Scilab has found a critical error (EXCEPTION_ACCESS_VIOLATION)
with "TCL_EvalStr" function.
Save your data and restart Scilab.
