However I have few issues - some minor and some very annoying

I use Notion with EW Gold orchestra, Garritan, KorePlayer (NI True strike percussion library) and Kontakt (some Bela D Media products). Computer: PC windows 7 64bit, core 2 duo 2.66, 6 gb ram, HD : 250GB and 1TB, Alesis io express.
1. At first cresc./dim. - Most of the times it doesn't work. I tried various ways like adding volume at first than adding hairpins or hairpins first then volume ,etc. It worked for me only few times.
2. there is also a big difference between dynamics p and mp. I'm not sure if it's just me, but mp is louder three times then p. and there is no so sudden difference among others. Is it normal???
3. when I use garritan instruments I use Modulation (CC1) to change volume. And I found that You can record and edit it only in real time, so You cannot edit these changes by painting lines or even change value of each CC. You have to record it again (real time only again). or I am wrong...??
4. Modulation (CC1) sometimes stops to work. When I move modulation well instead of expected volume change or timbre (EWQL Gold and DXF instruments), nothing happens or just a little. In this case I have to restart Notion.
5. Annoying windows of EWQL when Notion loads samples. I know - it's not Notion's issue itself, but.. is any way to avoid it? I have to click at least five times to confirm that there is not enough memory before project is loaded.
These are issues that I encountered so far, if anyone knows answers or maybe have some solutions please let me know, I would be very thankfully,

Cheers,
piotr.
