Summary: popup not working in windows (with workaround)
Initial Comment:
Ben Bogart's popup is not working properly in windows (PD-Extended 0.41).
It loads fine but it does not output a selection nor does using its inlet work to change its selection. Whenever you try to do so it gives the error:
error: popup0xa4fda0: no such object
I tracked the problem down and it seems that in windows TK doesn't like it when the pointer reference in hex starts with 0x. This might actually be a problem with the TK provided in the windows version and not with popup itself. In Linux and OS X the reference has 0x in it and works just fine.
Here's a workaround that fixes the problem.
diff popup.c popup.c.orig 
596,599d595
< #ifdef NT
< 	char buf2[256];
< 	char *buf2ptr;
< #endif
646,654d641
< #ifdef NT
< 	sprintf(buf2,"%p",x);
< 	buf2ptr = &buf2;
< 	if(strstr(buf2, "0x") == buf2ptr) {
< 		buf2ptr++;
< 		buf2ptr++;
< 	}
< 	sprintf(buf,"popup%s",buf2ptr);
< #else
656d642
< #endif
661,663d646
< #ifdef NT
<    sys_vgui("proc popup_sel%x {index} {\n pd [concat popup%s output $index \;]\n }\n",x,buf2ptr);
< #else
665c648
< #endif

Changes only in the popup_new function. It uses the NT preprocessing directive, in Linux and OS X it should remain unchanged. Basically it tests the pointer for 0x and removes it.
