also, you say that you are retrofitting your patches for vanilla, so, I guess I would have to interpret that as meaning you are using a version of pd that is more than five years old, which might be the source of at least some of your problems. I would suggest updating to the just released 0.48-2, as there are a number of features and improvements that have been implemented since back then, though perhaps I'm just being too generous in my interpretation of your comments, and your problem is instead that you are having some difficulties understanding the difference between pure data and the various forks which, with the exception of pd2lork (which is itself a fork of extended), are all no longer being developed.

you might want to start by using declare instead of import, which was an external which was distributed with the extended fork of pd, which was abandoned five or so years ago. and on that note, extended was a fork of the main pd distribution, so backwards compatibility doesn't really even enter the picture here at all, but if you are making comparisons then I think you'd have a difficult time making the argument that supercollider has introduced fewer breaking changes in that timeframe, at least if you aren't comparing apples to donuts.

Well, the first patch I could make it happen with in the externals folder was with the adaptive equalization example in the adaptive library's example folder (07.adaptive.equalization.pd). Trying to click the "open sample" gui bang on the pd input subpatch has no effect, and I have to open the subpatch before I can actually open a sample. There are more examples. I can find more, if you'd like. It seems to still be an issue with this release candidate. Also, the original problem that triggered my comment seems to still be an issue.

On Windows I'm having similar problems with sliders as well as bangs and toggles. Sometimes it seems bangs to asubpatch or abstraction don't work at all and i have to open it up and add a bang there.
