RE: [mat-dev] Latest builds

[Andrew Johnson <andrew_johnson@xxxxxxxxxx>]

I've tried the latest build MemoryAnalyzer-Incubation-0.8.0.20090615-win32.win32.x86.zip
and got the following error after installing
the DTFJ dtfj-updatesite.zip available from IBM developerWorks.
The error went away when I restarted
MAT with MemoryAnalyzer -clean

I don't know what caused the problem.
