[PD] ButtonRelease binding getting lost - was Tcl getting sluggish

[Pierre Alexandre Tremblay]

Ok now I hit a strange bottleneck. I hope anyone can help.

1. If I don’t delete the frame, tcl get sluggish like memory leak vibe

1a) I’ve tried
	 	if {[info exists %lx_frame]} {.x%lx.c itemconfigure …
	like I saw in the IEM - to no avail

2. If I delete everything in my draw routine (frame and points) I get happy, but

2a. My mouserelease binding disappears and doesn’t seem to accept rebinding.

I need that for the command-drag-to-zoom ending. During the drag it redraw all right, so the “motion” still gets send, but my redraw deleting the frame on which the original binding was done is delete and recreated and re-bind-ed but to no avail

Now, I’m really stucked. I have tried everything.

Any help is really welcome.

I think I got a hunch of needed to delete from IEM’s toggle (which has a new and update method) and that opens a can of worm of a full re-write on my side… is there any tutorial out there on writing GUI ? Or commented code? Or good practice?
