By default; the program bypasses single-process functionality and opens a new main window;$$$Added support for the `-a` command-line argument in the Solver application.$$$Corrections$$$Fixed copying of recently entered equations into a Math Region (previously returned incorrect results for non-invariant cultures);$$$Fixed language switching in Text Regions to preserve the original text formatting;$$$Fixed an issue where an invisible Message Box appearing in the background on connection errors would block the UI until manually located and closed;$$$Fixed the sorting of plug-in information when saving files;$$$Fixed a symbolic engine error that could cause incorrect signs for specific equation terms;$$$Fixed a critical issue where an unhandled exception occurred during user actions if the cursor was not properly positioned within a Math Region;$$$Pressing the Ctrl key while selecting inside a region no longer immediately selects the entire region;$$$Improved Math Region to support the `\`; `[`; and `]` characters in special character mode;$$$Plug-in dependencies are now accounted for when saving `.sm` files; even if the region is located in the header or footer (this resolves Viewer app generation errors);$$$Corrected the message order during the startup of silent-mode applications (in command line mode);$$$Fixed a calculation of `0 * (-8)` that previously threw a null reference exception; it now correctly displays an Uncertainty error;$$$Fixed calculations for `8/0` and `-8/0` that incorrectly displayed an Uncertainty error; they now correctly return an infinity value;$$$Made the plug-in ID optional for the `DataIn` and `DataOut` options of the `-o` command-line argument;$$$Fixed an issue that prevented the Account dialog from being closed;$$$Prevented UI hangs caused by modal dialog(s) from the main form appearing outside the main window and blocking interaction until located and closed;$$$Fixed an issue with vertical scrollbar thumb positioning in large documents;$$$Fixed vertical scrollbar bookmark positioning on high-DPI screens;$$$Improved the MSI installer to correctly register the version of the COM-visible API library in the Windows Registry and add missing 32-bit-related registry keys for 32-bit systems;$$$Fixed the Print and PrintTo file associations in the Windows shell;$$$
