Probably not intentional (unless Jon has been experimenting with the mescaline again), but if you have a "Move Window to Centre of Monitor" button on a common MsgBox modal window, and then you repeatedly click it, the window gets inexplicably larger and larger (as it centres), ad infinitum.

Run this as a .VBS file and you'll see what I mean...



Win 7 x64, v4.1.0 Beta 9 (though it started at least in Beta the 8th...)

No video, but a picture is still worth a thousand words, even in a century such as this.

Basically it's a progressive thing - each time the DF Centre button is clicked the modal is centred, but also slightly magnified. For example, the first image is normal - the second is after 4 clicks and the third is after 10 clicks.



At first I thought it might be a DPI issue (I use %125) but adjusting back to normal it continues to occur. It doesn't happen with all windows - only some - but always with modals such as the MsgBox above, regardless of which programme generates it (the VBS was simply the easiest method to reproduce it).

Considering it only happens when using DF's Centre button, and never occurred before Beta 8 (at least I didn't notice it before then), the cat would appear to be in DF's bag, no? (I don't use any magnification software nor anything else which might manipulate screen object scaling.)

Addendum: Just checked, and while it does happen under DF 4.0.1, it does not happen under an old copy of DF 3.4.0 I had laying around.

Done. Ran the VBS and consecutively clicked Centre 10 times. Makes for exciting reading (if one has a penchant for staying up too late and drinking too much coffee - and an acquired appreciation for the more droleful side of sardonic wit).

Ah - how humiliating, that rather obscure option was indeed activated - turning it off solves the (literal!) window bloating.

There's no reason I can think of off the bat why I would be using that option, except awhile ago I was experimenting with SendMessageW calls via User32.dll (using the AutoIt Language) when reading the text from the edit portion of a combo-box, and for some unknown reason DF was causing nonsense characters to appear at the end of the allocated array (this did not happen on other machines or with DF disabled), so I must have thought to myself "Hey, I know, let's try this option that's guaranteed to make things even more unstable!" (yeah, the things we do for fun).

Anyway, long story short, I never did discover why DF was interfering with the SendMessageW call, but I found an alternate workaround, and figured it would be way too esoteric a problem to raise on the forums, so the universe was at peace again. Except that I obviously forgot to de-select that rather grumpy rendering option, and it came back to haunt me.

So - no harm, no foul! Thanks for clearing that up - I'm reminded why my mum taught me to look both ways before crossing the street by myself. (Something about not leaving one's shoelaces experimentally un-tied comes to mind...)
