Hey! This screen looks cool! Could you please provide your .conf? (good 
to know what cool designs are possible with my NextGeneration layout)

6 secs? strange...

Right.

I took a quick look over the code, but I found no error here. Please try 
the following:

in your plugin_xmms.c, at line 96, add a line between
   if (age>0 && age<=100) return 0;
and
   // Open Filestream for '/tmp/xmms-info'

which reads
   debug ("DEBUG: re-reading /tmp/xmms-info...");

and start lcd4linux with -F -vv

it should print out the debug message every time the file is re-read. 
You could add other debug messages at certain points, too. the debug() 
functions acts just like a printf(), that means you can print 
parameters, too:

debug ("Hi %s", name)



bye, Michael
