but I've got one and this seems to be the logical forum to use. The latest v8.0.48 at the end of an online defrag, PD freezes and fails to pop up the Summary dialog box. After many clicks on "End program... not responding" PD finally closes. The same thing happens after just "Analyze" only is performed. After reopening PD, the log says the defrag was 100% Uninstalled/reinstalled didn't solve it. The 'repair' didn't work either, instead of uninstalling. The offline defrag works properly. Tried going back to v7.0.46 and that worked OK...it didn't freeze and produced the summary box at the end. In both v7 and v8, I have 2 $ISR snap shots excluded. Also have FDISR, Comodo FW, NOD32 (no Norton) Any ideas?
