Thanks for the reply, Paul.

I hadn't changed "cd %TRIO_HOME%", but your other suggestion worked......kind of.....

Using your suggestion, the Java web interface now loads, but the player tab doesn't change the display from what it is on the status tab.

It doesn't work on my other machine either. And nothing seems awry (to my untrained eye) in the Java dos window:

---------------------
Got http request: GET /trio-applet.htm HTTP/1.1
Got http request: GET /trio-applet-0.1.4.jar HTTP/1.1
Got http request: GET /images/rio-small.gif HTTP/1.1
getting image: file:/C://Program Files//trio-0.1.4.alpha5/images/rio-small.gif
Updating config file
---------------------------

Although, actually, there *is* something a bit funny when tRio first boots, but that doesn't seem to affect any other operation.
----------------------
C:\Program Files\trio-0.1.4.alpha5\bin>set TRIO_HOME=c:\Program Files\trio-0.1.4
.alpha5

C:\Program Files\trio-0.1.4.alpha5\bin>set JAVA_HOME=c:\Program Files\Java\j2re1
.4.2

C:\Program Files\trio-0.1.4.alpha5\bin>cd c:\Program Files\trio-0.1.4.alpha5
Too many parameters - Files\trio-0.1.4.alpha5
-------------------------------

"Too many parameters"??

So sorry to keep pestering you like this! I thought I had a bog standard set-up but I must be doing something wrong to have so many problems! Unless maybe the fact that I'm using ARM is the problem...?

Thanks again
