Sneaking around trying to find out what is going on with Vue 4 I found this tiny tidbit... "SolidGrowth2 is a clean improvement on the SolidGrowth engine. If you bought some of those extra plants from the e-on software website, you'll be able to use them in Vue 4 AND gain some improvements from the new SolidGrowth2 engine -- they will look even better under Vue 4" -Lynn Fredricks of E-On Software, U.S. ********************************************* So, I assume all your plant work, will work in Vue 4. Apparently the older stuff won't be made obsolete...
