|
* Demonstrates a conhost hang that occurs when widening the console buffer
|
|
* while selection is in progress. The problem affects the new Windows 10
|
|
* console, not the "legacy" console mode that Windows 10 also includes.
|
|
*
|
|
* First tested with:
|
|
* - Windows 10.0.10240
|
|
* - conhost.exe version 10.0.10240.16384
|
|
* - ConhostV1.dll version 10.0.10240.16384
|
|
* - ConhostV2.dll version 10.0.10240.16391
