Yes that's it. The other change was an improvement to resizing. This is long and tedious so feel free to ignore, but if you're curious then here are the details. Typically window managers treat windows as one of two flavours: 1) The program set the size, so it's permitted to change it again itself. 2) The user resized the window, so the application request to resize it will be ignored. Tk wm geometry command allows you to programatically change the size of window or with the blank size (wm geometry . {} {}) it'll reset the window to case 1 - governed by the program rather than the user. This is all very ICKY and it gets worse. Gap4's contig editor is "courageously" setting the Y dimension itself based on how many rows of sequences it wants to display. The X dimension can be controlled by the user, but as the user increases the size in X, more sequences can become visible causing the Y dimension to be resized. In the past this caused massive fights between various parts of tcl/tk and window managers, sometimes triggering event loops with oscillating window dimensions. The workaround for this was to have a 1 second delay between resizing the window and asking the program to recompute the size. That in turn though broke all modern window managers. Basically if you resized quickly and let go it'd just snap back - you had to resize, hold and wait for 1 sec, and then release. Bizantine... Try hard as I may I couldn't recreate the strange oscillations so this change basically pushes it back to how it used to be with instant recomputation. It seems to work much better in general, but still isn't perfect. Perfection isn't possible when you start with the premise of X being user controlled and Y being program controlled! With Gap5 fortunately we had an attack of sanity and chose a more traditional strategy. James PS. Kerstin if you're still reading this, if set -x doesn't work then just editing the first #! line to be "#!/bin/sh -x" (without the quotes) should do the same thing, or simpler still typing in sh -x `which pregap4` -- James Bonfield (j...@sanger.ac.uk) | Hora aderat briligi.
