Freezing occurs when running an MS-DOS window on Win95 OSR2 or later Windows, rather than the original Win95. This doesn't happen on the original Win 95.

This has always happened with Windows 98 SE as well and it looks like a DOSBox issue, not a DOSBox-Pure issue. You can sometimes avoid the freezing by significantly lowering the CPU cycles, like setting the Performance to something like 33MHz, but it will still happen often.

@PoloniumRain Surprisingly, this phenomenon did not occur in the 2012 build of DOSBox SVN Daum.
