NO "Instability"! (Miscellaneous)

"Everyone else" DOES NOT need to download UPX. XMGR and UIDE load properly
using the CONFIG.SYS file without any use of UPX. As it compresses a file,
UPX adds its own decompression code, thus the main UPX program is NOT NEEDED
by compressed files at load-time.

And using UPX for object-file compression has NEVER caused ANY "instability"
of which I am aware. If this were so, I would not be using UPX.

XMGR and UIDE are DOS system drivers, meant to be loaded thru the CONFIG.SYS
file. They load very early in CONFIG.SYS, and the system almost-always has
enough room for them.

Loading XMGR/UIDE (or ANY .SYS drivers!) at times OTHER than thru CONFIG.SYS
could occur when DOS is low on memory. The drivers may then be placed into
areas which hold the object-file BUT NOT the uncompressed driver. For such
cases -- AND ONLY SUCH CASES!! -- uncompressing the drivers may be required.

Users who DO NOT "play games", and who load XMGR and UIDE as .SYS files thru
CONFIG.SYS as the designers of DOS intended, DO NOT need to "uncompress" the
drivers, DO NOT need an actual UPX program, and will have NO problems caused
by UPX usage.
