VisixSoftware Inc is pushing ahead in the heated desktop manager race by putting its Looking Glass interface under Sun Microsystems’ SunView, and going after what Visix management reckons is 90% of the Sundominated workstation market. The company also feels that bitter rival IXI Ltd won’t be able to follow it there. The software, which will impart a Motif look-and-feel to Sun machines, should be immediately available, at $700. Visix has also been going direct after big end-users, backed by a 15-man sales force, and expects to be announcing some big hits soon. A $100,000-a-month advertising campaign, directed at large accounts, should kick off in May.
