touchpad problem

Hi

I've been a lurker here for a good few months now and finally was able to get a miniplayer just over a week ago.

In short, I love the player, but I am having a major problem with the touchpad. When I have just turned the player on, the touch pad works perfectly but if I use the player constantly for a length of time, the touch pad just stops working properly. I cannot scroll or use it for any useful purpose and the only way to clear this seems to be to turn the miniplayer off for a while and let it "cool down" as it were. The clicky buttons continue to work fine.

I have tried using the touchpad calibration, but either I'm not using it correctly or it does nothing or at all, and I still have to resort to turning it off and leaving it alone. If I turn it off and on again in quick succession the problem does not go away, I actually have to leave it for a while. The problem shows up after playing about 30 minutes of video and after about the same length of time (maybe a little longer) of playing audio.

Has anyone else encountered a similar problem? I can't really determine for sure if it is a hardware or software problem. I had the thought that it might be an overheating problem which could affect the touchpad functionality.

I bought from houseofdap.com and presumably they will honour any warranty but I don't relish the idea of returning it, particularly at this time of year, so any ideas, help or advice would be greatly appreciated.

tried a firmware upgrade?

It arrived with the latest version as far as I can tell.

doesnt matter, sometimes problems are related to firmawares loaded incorrectly.

Try loading firmware, be aware about Miniplayer's version, TP or SP

I tried reloading the firmware to no avail.
Further, I had to recharge the battery for the first time last night, which I did using the external battery pack. The problem is, after this the touchpad is now completely unusable, so I think I'm looking at a warranty returns situation

Try and reset the player

no luck there either
