- snapObjectToCenter() enhanced to accept groups in [snapToName]
- NEW function: onFirstIdle()
Detects when browser has entered an idle state and all objects have been loaded. This is very similar to notifyAfter firstIdle in openScript. - Fixes IE 11 for all ToolBook versions. Modifies bootstrap.js. Bypasses fix if SumTotal patch is already applied in ToolBook v11.5.
- Fixes some additional IE bugs when enabling "Enable IE HTML 5 Display"
- Fixes a bug in all ToolBook exports for non-MSIE browsers (notably Firefox) wherein a non-fatal DOM exception occurred while loading content.
NOTE: This is a relatively rare condition but we experienced it during development of another project. - VideoJS HTML 5 player engine updated to v4.3.0.
- NEW function: pgArrayToString()
Permits conversion of arrays to strings separated by custom separator strings. Performs an opposite function to pgSplitToArray(). - pgTBObjSet() modified to better work with web fonts when setting button captions.
- Exports are time stamped to assist browsers in determining whether to load cached or fresh content.
- IE content now supports transparency when "Enable IE HTML 5 Display" is checked in the PowerPac menu.
- Improved behavior of setTreeMenu() when deleting tracking data.
Current selection is never deleted and remains highlighted if highlight styles were previously defined. - BUG FIX: pgGotoURL() can now load external content in EITHER a new browser tab OR a popup window.
