• Fixed water block export for T3D (see post).

• Add ability to define filters from script files, with example zfilter files included with installer.

• Fixed bug when using 'Operations→Texture map→Generate map' option to generate mosaic texture without first having saved project (see this thread).
• Fixed thin transparent margin in 1st pane in wizard (using SWP_FRAMECHANGED flag).
• Revised auto-flooding of lakes to work properly with small horizontal scales, and use improved lake search/test algorithm.
• Fixed lin interp to not mangle edges on wrapping maps (see bug report).
• Fixed bug that caused memory corruption when % symbol was present in filename.
• Fixed preservation of variable parent handle when lists are edited via var_EditUI.

• Modified L3DT to store default resources in installation directory, and copy to users' profile directory when new version if first used. This allows multiple users/profiles on same machine to use L3DT (see request).
• Created new 'SilentError' flag for plugin settings, to allow plugin loading to fail silently (used for 'ZeoPerfMon_NT', which is now enabled by default).
• Added check for whether 'ZeoPerfMon_NT' plugin is enabled when opening ram chart (a la CPU throttle).
• Modified InflateMosaic function to take file config arg as hvar (if NULL, HFZ is used), and allow null map and file names (auto-generated).
• Improved startup speed by storing plugin crash flags in separate files per-DLL, rather than saving whole extensions.ini.xml file.
• Modified extension manager window & command line parser to support re-loading of plugins.
