FAQ.How to avoid leaks with Cocoa functions?

// in a Timer Action event:
Sub Action()
  static LastPool as NSAutoreleasePoolMBS = nil
  static CurrentPool as NSAutoreleasePoolMBS = nil
  
  LastPool = CurrentPool
  CurrentPool = new NSAutoreleasePoolMBS
End Sub

With Xojo 2009r4 the code above should not be needed as Xojo runtime does automatically handle the NSAutoreleasePools for you. For older Xojo versions you need to use code with a timer with the action event above to avoid memory leaks.

Please do not use Xojo 2009r4 and newer with plugins before version 9.5. You can get crashes there which typically show a line with a objc_msgSend call.
