<br><font size=2 face="sans-serif">Hi,</font>
<br><font size=2 face="sans-serif">I've installed the opencms (Tomcat (5.0.16), MySQL (4.0.17) and opencms (5.0.1)) environment on W2K. I'm trying out "the demo" listed in Ch 5.2 section 1 of the opencms manual. The step  to  "Edit pages" fails. On different installation/test run phases I get different results. Here's the most common:</font>

<br><font size=2 face="sans-serif">Note that I'm using Tomcat 5.0.16. I get a compability warning during installation saying that opencms has not been tested against it. Is this the problem?</font>
<br>
<br><font size=2 face="sans-serif">Thanks for any help on this,</font>
