Problem solved. Thanks a lot !!

I think I found out why you don't see any leak. Please goto "advanced system settings" -> "performance settings" and check "show window contents while dragging". I made some experiments starting with an empty form and then adding a spkToolbar then spkTab etc. My conclusion is that when images are connected to spkLargeButtons (and window contents are shown while dragging) there is memory leak. According to task manager the program starts with 3.2 MB and when the size reaches 40 MB there is an error...

Lazarus version=1.9.0 2017-08-19 FPC version=3.1.1 SVN Revision 55677M Open project spktoolbar\demos\actions\project1.lpi Build and run program Open task manager to watch memory size of project1.exe Use the mouse to grab the right border of the application window and start increasing and decreasing the width of the window. Notice at the task manager that the size of memory of project1.exe increases.
