@jona I did another wipe of the registry and a fresh install of the 64 bit, and I'm no longer having this issue. I wish I knew what actually caused it, because I hate when a re-install magically fixes things, but here we are...

Well now I'm having all sorts of trouble getting externals working. Gem is throwing errors, some parts of iemlib are missing, or just not working.
.. I'm re-installing them using deken, so they should be the 32 bit versions. Maybe I'll try deleting all those registry entries again and give the 64 bit another go?

I can confirm 32 Bit does not have the same issue. I've moved my old externals into a 64 bit folder, in case I decide to go back.
weird...
thanks!

@jona - interesting, thanks. I was going to try 32 bit just for kicks. In that case, I have to use Deken to re-download any externals that use compiled dlls, right?

@jameslo - I'm on the latest version .50-2. Mac hasn't launched new instances for as long as I can remember. Linux I'm not sure, I feel like I've seen it go either way.

@whale-av - Mine had Pd as the default application. I changed it to Wish, but it behaved the same. Same thing as doing a right-click 'open with': Both Pd & Wish will launch a new instance.

My registry entries all seem pretty straightforward, but I think I'm just going to nuke them all and try a fresh install.

unrelated - any reason to consider 64 Bit over 32 Bit versions or vice versa? I'm on a 64 Bit OS, but can't imagine a scenario where I'd need more than 4GB for PD.

Hello -
When I double-click on a .pd file in OSX or Linux, it will open a new instance if none is running, and any subsequent files are opened in the same instance. In Windows, every time I open a file from explorer, it launches a new instance.
Is there any way to stop this, and make it behave as it does on other platforms?
thanks!

I've been tinkering with Context Sequencer, which warns against changing the fonts and I think zooming.
I'm also just happy to get back into 'rolling my own' after being away from Linux for well over a decade.

@seb-harmonik.ar - exactly what I was looking for. The build was pretty straightforward, and increasing those values by 2 pixels makes it noticeably easier.
Thanks!

Wonder if there's any other UI annoyances I can fix now that I've got a working build...

Worth a try, but didn't work - the object is larger, but the inlets & outlets are the same size.
