ZXbox Loading problem

[Reece]

I downloaded some .tzx files to play on ZXbox on my sansa clip+, but they load very very slowly and it seems to be glitch, because it gets up to 99% and stays there. Can someone help me?

Hi All,

I have the same problem with my Clip Zip.  I've tried to open some .tzx and .tap files.  They load up to around 67% and then get stuck.
When I select quite,  I get the message:
Plugin returned error leak-file-handles

Any ideas what's bugging?
Thanks!
