Basic question: sending patch, bank changes in Logic Pro 7.1

Question

I find that when I use Logic's Track Mixer to assign patch and bank information to a midi track, my sound modules (usually an old Roland SC-8820 and a new Korg Micro X) play what they are supposed to (though I don't have a multi-set for the Korg yet, working on one). But when I save my Logic song, close Logic and reopen the song, the correct patch and bank info is not necessarily sent to the synths. The Track Mixer correctly shows my patch and bank settings (in the CC#00 and CC#32 boxes, etc.) but these banks and patches don't play -- unless and until I go ahead and click in those MSB or LSB boxes in the Track Mixer. I don't have to change anything, just click. Then apparently the Track Mixer sends the patch information and my synths play what they are supposed to play. Is this the way Logic always works? Is there anything else I can or should check or uncheck? (It's a drag, when working on a song with a lot of tracks, to have to click every track again every time to get the right patches playing.)

Thanks for the suggestions, but things still aren't working. To implement what I think you are recommending:
In the Logic Pro menu, Preferences, MIDI submenu, Reset Message tab, there is a checkbox for "Send Used Instrument Settings on Reset." I've checked it.
In the File Menu, Song Settings, MIDI submenu, General tab, there is a "After Loading Song Send __ Used instrument MIDI settings" checkbox. I've checked it, too.
But with both checkboxes checked, I still don't get the right patches when the song loads -- yet, as before, just clicking in either MSB or LSB boxes in the track mixer seems to send the values I've previously put in those boxes, and the song plays as it should.
As to the other idea: by "insert the instrument settings into the beginning of each track," I am thinking that you mean choose "Insert Instrument Settings as Events" from the MIDI menu in the arrange window. Went there, did that. But for some reason after I do so my events list gets amended to show the patch I've selected for that track in the Track Mixer, but not the MSB or LSB -- CC#00 or CC#32-- settings I entered in the Track Mixer.
Suggestions?
