5 problems found in Ti V3

[L.F.]

1. Loos of sync, sync "drift", LFO/Arp not synced to tempo.
All of these occur ony occasionally and only with some patches\projects.

2. Hanging notes.
No logical reson found; not dsp related, no midi anomalies, starts randomly and not every time.

3. Patch volume(s) different after reload.

4. Either the Ti cut's voices off for no reason of the New OS uses more DSP.

5. Completely random pops/clicks during playback.

All of these problems occur in Cubase SX3 + WinXP SP3 (fresh install).
Asus Commando, c2d@3.6 GHz, 2GB DDR2. (hardware tested and working)
The problems are not latency, midi, background tasks, usb port/cabel. These have been checked.

If anyone's got any tips on how to fix any of these, I'd appreciate it.
Also if any of these are a known bug that's being fixed, do tell.
