As some of you already know, I have added Long File Name (LFN) support to DOSBox last month. Both the DOSBox shell commands and many native LFN-aware DOS programs should now be able to use LFN in DOSBox. However, another useful feature that is missing in the original versions of DOSBox is the ability to copy and paste text in DOSBox by mouse. So since yesterday I went further to add mouse copy and paste support to DOSBox. You can now use the right mouse button to select, copy and paste text from and to DOSBox (when the mouse is not locked). The DOS APIs that communicate with the Windows clipboard are now supported too (e.g. you can copy and paste text using 4DOS's clipboard feature via the CLIP: device name).
See the attachment for the binary, along with all required DLLs.
EDIT: For the latest build, please download the Windows binary from (updated April 2020): dosbox-svn-lfn.zip
Also look at the later pages for recent improvements related to this feature.
The Windows binary now also includes features such as automatic drive mounting, direct LPT passthrough, APM power off, DBCS and LFN support in addition to mouse copy/paste support.
