Hello all, A small report : The "VALUE_EDIT_CB" of the IupMatrix (tested with IupMatrixEx) seems to have some kind of issue. I'm using it in C++ with the IUP_DECLARE_CALLBACK, IUP_INITCALLBACK and IUP_SETCALLBACK (which by the way work very fine for all other callbacks). Sometimes, this one works ok. But at some point, it blocked my std output stream (i was printing the values of course). Not sure why. I could see that it printed some 0 values at startup, and then the output stream was blocked for all the application (I couldn't even use cout in another class or anything).
Finally I Use the "LEAVEITEM_CB", which is almost the same in my case. I hope it can help. Johann
