I use
Open CPN 2.4.324 as I use encripted BSB4 Canadian
Charts for North West
Passage. It worked since March well.
Just to day this version slowed down to molasses and indexing takes ages into unknown.
Practically to do any measurements and panning is the chore. Picking any tools item also takes extra time.
Checked my computer for any viruses and there are none as well as registry for unwanted entry. Removed all
BSB coastal
charts from viewing and other except for cm93. I am running under XP SP3. With 2 Gb RAM the use of it is only 0.5 Gb. Any clue ?. Thanks for support.
